Mishimoto NonThermostatic Oil Cooler Black Ford Focus ST13+

NonThermostatic oil cooler for the Ford Focus ST (13+) engineered to address rapid oil overheating during sustained high-load driving, preserving oil viscosity and component lubrication under track and aggressive street conditions.

This Mishimoto NonThermostatic Oil Cooler is specified for turbocharged, high-stress 2.0L EcoBoost applications where the stock liquid-liquid head exchanger can be insufficient to prevent elevated oil temperatures. It provides an additional dedicated cooling path to help manage oil heat soak that can occur within only a few laps or during aggressive driving.

Why this matters

Turbocharged four-cylinder engines can push oil temperatures quickly into ranges that affect film strength and long-term component durability. Adding a non-thermostatic cooler removes reliance on engine coolant temperature and head-exchanger capacity alone, offering consistent oil cooling during sustained high-load operation.

Key functional benefits

- Direct oil cooling focus: reduces thermal load on engine oil during repeated high-RPM or track use, helping maintain lubricant performance and reducing risk of heat-related oil degradation.

- Non-thermostatic operation: provides continuous oil flow through the cooler whenever the oil pump circulates, avoiding the potential delay or restriction of a thermostatic bypass under prolonged stress.

- Application-specific fitment: intended for Ford Focus ST model years 2013 and later, designed to integrate into the vehicle’s existing oil and routing architecture.

Performance context

Used alongside factory cooling systems, this Mishimoto oil cooler augments the vehicle’s ability to control oil temperatures in scenarios where the stock liquid-liquid head exchanger may not be sufficient on its own. The product is positioned for drivers performing track days, spirited driving, or turbo upgrades that increase thermal demand on the engine oil system.

Brand and build intent

Mishimoto designs cooling components with a focus on motorsports-derived functionality and long-term serviceability. This oil cooler is presented as a performance-oriented component intended to improve oil thermal management in applicable Focus ST 2.0L EcoBoost configurations.
